I have the exact opposite problem. I'm very "talkative" and outgoing online, but in real life, I'm quiet. A few days ago, though, I started acting like my online self IRL, and it was kinda nice. I think part of the reason I'm not a big talker is because of my mom. She likes to monopolize the conversation, and really doesn't care to listen to others, unless there's something she wants to know. She's kinda immature that way. Blah. Anyway, I'm just glad I'm finally, maybe, hopefully, learning how to open up.

I'd ditto the advice given. Just kinda post all over, be polite and kind and friendly, and see what happens. People have PMed me and started conversations. It's been really nice so far. (I'm pretty new here, but I've been in other forums before.)
